The main problem is HC-05 baud rate. It is possible to change that, but it is not that simple.
You will need a computer with true parallel port, some resistors to make a super simple schematics to connect hc-05 to parallel port and some software.
I got instructions how to do it, but haven`t try it yet.
If you`re interested I can give you some detail information.
